Introduction to twisted cable


Twisted cable wire is generally made of two 22-26 gauge insulated copper wires twisted with each other, and the name "twisted pair" is also derived from this. Two insulated copper wires are twisted together at a certain density, and the radio waves radiated by each wire during transmission will be offset by the radio waves emitted by the other wire, effectively reducing the degree of signal interference. In actual use, the twisted-cable wire is wrapped in an insulated cable sleeve by multiple pairs of twisted-pair wires. If one or more pairs of twisted pairs are placed in an insulating sleeve, it becomes a twisted pair cable, but in daily life, the "twisted pair cable" is generally directly called "twisted pair". Compared with other transmission media, twisted pair cables are subject to certain restrictions in terms of transmission distance, channel width and data transmission speed, but the price is relatively low.
